IMAGE SIGNAL PROCESSING DEVICE

摘要

PROBLEM TO BE SOLVED: To reduce line memories in removing block noise and mosquito noise in noise removal for a compressed image.

SOLUTION: An image signal processing device for removing block noise and mosquito noise generated by image compression from a digital image applies block noise removal, then removes mosquito noise, and performs edge detection processing for mosquito noise removal using line memories holding input lines for performing block noise removal.
